[Pkg-acpi-devel] Bug#565908: acpid: causes Xorg to hang because of "too many connections"

Tue Jan 19 15:36:46 UTC 2010

Package: acpid
Version: 1:2.0.0-1
Severity: important

My machine is up since 5 days with about 10 hibernate sessions since that time 
- I could look at the logs to get the exact number.

After hibernate (uswsusp), the X Server hangs. That means, I just got the message
from s2disk on the otherwise black screen, and the input devices do not work 
at all, especially no Strg+Alt+Fn. 

So I logged in via ssh and got the following backtrace from the Xorg process:

 bt
#0  0xb77c4424 in __kernel_vsyscall ()
#1  0xb7775241 in connect () at ../sysdeps/unix/sysv/linux/i386/socket.S:61
#2  0x0814cdfa in ?? ()
#3  0x0814c17d in xf86OSPMOpen ()
#4  0x080b187c in xf86Wakeup ()
#5  0x0808a332 in WakeupHandler ()
#6  0x080a0b7a in WaitForSomething ()
#7  0x08073dc0 in ?? ()
#8  0x0806695a in _start ()

I had a similar problem about 2 weeks ago where I was able to see that it tried
to connect to the acpi daemon. Don't ask me how it found that out.

So I restarted the acpid daemon. Immediately, the X session was back and 
usable again. I looked in the syslog and found:

# grep -i acpi /var/log/syslog

I may be able to provide more information, but the problem is that it requires 
some hibernating to actually reproduce this problem. (And I'm not sure if that's 
enough to reproduce the problem)
